To all whom it may concern: 7

Be it known that I, LoUIs C. KRUMMEL, a citizen of the United States, residing at Clinton, in the county of Middlesex, State of Connecticut, have invented certain new and useful Improvements in Devices for Feeding Can Ends to a Seaming Mecha nism, of which the following is a description, reference being had to the accompanying drawing and to the letters and figures of,

reference marked thereon.

The invention relates to new and useful improvements in devices for feeding can ends to a seaming mechanism, wherein the can end is secured to the can body, preferably by a double seam.

An object of the invention is to provide devices on which a canend may be placed, which devices are moved in timed relation with the parts of the seaming mechanism so as to position the can end between the can body and the seaming mechanism. A further object of the invention is to provide means for temporarily supporting the can end beneath the seaming head until said can end is engaged by the chuck of the seaming mechanism.

These and other objects will part be obvious, and will in part be hereinafter more fully described.

In the drawings which show by way of illustration one embodiment of the invention, Figure 1 is a front view of a portion of a double-seaming machine having my improvements applied thereto; Fig. 2 is a side view of the same; Fig. 3 is a side view of the supporting end-feeding device; Fig. 4 is an enlarged detail view, showing the end of the carrier and the manner of supporting a can end thereby; Fig. 5 is a detail showing the position of the carrier when the ends are placed thereon.

The double-seaming machine herein shown consists of a standard 1, in which is mounted a shaft 2, carrying a bevel gear 3 at the forward end thereof, which bevel gear drives a second bevel gear ion the spindle 5, which carries a seaming head 6 at the-lower end another to a position underneath the seamng head, where they are held stationary durmg the double-seaming action. The can body and can end are centered relative to each other and relative to the seaming head, by centering jaws 9, which are mounted on a shde 10, which slide in turn is reciprocated by a rod 11. The rod 11 is connected to an arm 11 which is attached to the shaft 11. This shaft 11 is oscillated by an arm having a roller running in a cam groove in the disk 11 The disk 11 is carried by a cross shaft 11", which in turn, is driven by a gear and worm connection with the main shaft 2. The cross shaft 11 also carries an arm 11 which reciprocates the seaming head, and, therefore, the seaming head will be reciprocated in unison with the slide 10, carrylng the centering jaws. These centering jaws and the parts for operating the same are largely similar to those shown and described in the patent granted to L. G. Krummel and J. C. Taliaferro April 12, 1910, #954,976, and further detailed description of the structure and operation will not be needed.

As disclosed in this patent, the filled cans are placed on the drum feed and brought one after another under the seaming head, whereby the heads or ends are doubleseamed on to the can bodies, after which the closed cans are discharged from the machine. Prior to my invention, it was customary to place the can end for closing the can on to the filled can as it was conveyed to the seaming station. These ends were often dislodged from the can or caught by the seaming head, which materially limited the output of the machine. By my improved device, the can end may be carried directly under the seamin head and positioned relative to said seammg head and filled can. I have also provided devices for temporarily holding said can end until engaged by the chuck and seated in the can body. Said endfeeding devices consist of a carrier 11, which is mounted to reciprocate in a supporting bracket 12. Said carrier consists of a dovetailed plate 13, which fits in a. dovetailed groove formed in the supporting plate 14, which is vcarried by the bracket 12. The bracket 12 is secured to the standard 1 of the double-seaming machine by bolts 15.

Adjustably secured to the upper face of the plate 13 is a bracket 16. Said bracket is slotted at 17, and a bolt 18 carried by the plate13 extends through said slotted bracket and serves as a means for adjustably securing said bracket to said carrier plate 13. A vertical shaft 19 is mounted in a bearing bracket 20, secured to the standard of the double-seaming machine, and in a bearing 21 formed in the bracket 12. This shaft 19 at its upper end is provided with an arm 22, which carries a roller 23 running in a cam groove 24 in a disk 25, mounted on the cross shaft 11 of the double-seaming machine. This cross shaft 11, as above noted, is driven through a gear and worm connection from the main shaft 2.

The shaft 19 at its lower end carries an arm 26, whichis connected by a link 27 with the bracket 16. As the main shaft of the double-seaming machine rotates, the shaft 19 will oscillate, which will in turn reciprocate the carrier 11. The carrier 11 at its forward end is formed with a lower forwardly projecting supporting ledge 28, on which the can end 29 rests. A ledge 30 projects over the ledge 28, and serves to hold the can end in place on the ledge 28. When the carrier is retracted or moved to the extreme left, as viewed in Fig.- 1, the supporting ledge 28 is opposite an edge gage 31, which is adjustably secured to .the bracket 12 by a bolt 32. The can end may be placed on the supporting ledge 28 by the operator. The can end is placed underneath the ledge 30 on the supporting ledge 28, with one edge of the can end against the edge gage 31. As the shaft 19 oscillates, the carrier will move forward to the position shown in full lines in Fig. 4, which will carry the can end underneath the seaming head. The ledge 28 andv overhanging ledge 30 are so proportioned that the can end is held li tly between these parts and supported so that it may be moved underneath the seaming head into sustaining jaws. The gri ping of the can end by the sustaining jaws will,

however remove the canend from the supporting ledge. It will be noted that the carrier and the supporting ledge for the can end are so constructed that when the can end is supported thereon, opposite side edges of the can end are free so that they can be gripped by the supporting jaws.

Mounted on the bracket for supporting the centering jaws is a plate 33. Pivotally connected with the plate 33 is a jaw 34,

stops 37 limit the inward movement of said jaws. These jaws 34 and 35 are disposed 1n substantially the same plane as the upper face of the carrier for the can end, so that when the can end is brought underneath the seaming head,-said end will be moved into the retaining grooves in said aws 34 and 35. The can end will be temporarily supported by these jaws until the chuck on the downward movement of the seaming head engages said can end. The supporting jaws 34 and 35 will move downward with the centering jaws, in the manner described in the patent above referred to, and, therefore, the can end will be firmly held and centered over the can body which is to be closed, so that the chuck will with certainty carry the can end into the open end of the can body. The centering jaws are cut away as clearly shown in Figs. 1 and 4, soas to provide a space for the jaws 34 and 35. The can end will therefore, be centered by the portions of the centering jaws which project above and engage the can end. The aws 34 and 35 will yield to allow this centering of the can end.

The adjustable connection between the carrier and the bracket 16 for the purpose of varying the position of the carrier for different sized can ends, whereby the carrier may be adjusted to a position so that when the carrier is at the forward end of its stroke, the can end carried thereby will be substantially centered underneath the seaming head. The edge guide 31 is also ad-' justable for different sized can ends.

While I have shown my carrier for can ends as adapted to receive pan ends placed by hand one at a time thereon, it is obvious that said carrier may be used in connection with a support wherein can ends are stacked and automatically fed onto the device. It is also obvious that minor changes in the details of construction and arrangement of parts may be made without departing from the spirit of my invention, as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The'combination of a can support, a seaming mechanism located above said support and including a seaming head,-mounted to rotate about a fixed axis and having seaming rolls, means located beneath the seaming head and supported independently thereof for receiving a can end and centering the same relative to the seaming head, a carrier having means for supporting a can end, and means for reciprocating said carrier, whereby a can end placed thereon may be carried underneath the seaming head and placed on said can end receiving means.
